Java SE (Java Platform, Standard Edition)

Hi,

Many times, this question has been asked by so may people, yet, till now, no solution has been given. I am posting this query in the hope that, somebody might have already done it.

Problem Statement:
I have an http server to deploy my applet ( in fact a signed jar ) that will ask the client to upload files from his local machine. Is it possible using only output streams ( such as DataOutputStream, FileOutputStream) ? I have managed to write the file ( converted to bytes ) to the output stream, but not able to save it on the server as a file.

How do I do it? I'm pasting my code here :

import java.net.*;
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;


public class FileUpload extends Applet implements ActionListener{
	URL url;
	File sourceFile, destFile;
	FileInputStream fis;
	URLConnection connection;
	DataOutputStream dos;
	FileOutputStream fos;
	Button b;
	byte[] buffer;
	public void init(){

		try{
			
			url = getCodeBase();
			connection = url.openConnection();

			if (connection instanceof HttpURLConnection) {
				System.out.println("This is HttpURLConnection");
				((HttpURLConnection)connection).setRequestMethod("POST");
			}


			connection.setDoInput(true);
			connection.setDoOutput(true);
			connection.setRequestProperty("Content-type", "multipart/form-data");

			
			dos = new DataOutputStream(connection.getOutputStream());
			sourceFile = new File("D:\\myFile.txt"); //this has been hard coded for testing purpose
			buffer = new byte[(int)sourceFile.length()];
		
		}

		catch(MalformedURLException mue){
			System.out.println("MalformedURLException occured");
		}

		catch(IOException ie){
			System.out.println("IOException occured");
		}
	
		b = new Button("Upload");
		b.addActionListener(this);
		add(b);
	}

	public void actionPerformed(ActionEvent ae){
		if(ae.getSource()==b){

			try{
				dos.write(buffer,0,buffer.length);
				System.out.println("Bytes written so far = " + dos.size());
				dos.close();
				
			}
			catch(IOException ie){
				System.out.println("IOException occurred during file transfer");
			}


		}


	}

}

I tried using FileOutputStream too by appending the destination file name to the url, but it was not possible to convert the URL object to a File oblject.

And another thing, I don't want to use servlets/JSPs at the server. I know how to upload files from applets to servers using servlet/JSP at the server side, to handle the requests.

The http server for my application has limited functionality and is not a servlet engine.

Thanks in advance.
